Can You Use Kerosene in Diesel Engines?

kerosene Paris, MERunning a fleet in Central Maine means dealing with brutal winters, demanding worksites, and the constant pressure to keep vehicles moving.

When diesel supplies feel uncertain or temperatures drop fast, it’s tempting to reach for kerosene as a substitute. Here’s what you need to know before you do.

What industries in Central Maine rely on diesel?

Diesel powers a wide range of Central Maine operations, from logging and agriculture to construction, transportation, and municipal services. Schools and government agencies rely on diesel for bus fleets and maintenance equipment. Gas stations depend on steady wholesale supply to keep customers moving. Each of these industries has too much at stake to gamble on fuel substitutes.

That’s exactly why reliable diesel supply matters more than most operators realize until something goes wrong.

What’s the difference between kerosene and diesel fuel?

Kerosene and diesel fuel are both petroleum distillates, but they’re refined differently and designed for different purposes. Diesel fuel has a higher energy density, which means more power per gallon. It also contains lubricating additives that protect fuel pumps, injectors, and other critical engine components.

Kerosene burns cleaner and has a lower freezing point, but it lacks the lubricity of diesel. Over time, running kerosene through a diesel engine increases wear on fuel system components, costs that far outweigh any short-term savings.

When is mixing kerosene with diesel acceptable?

There are situations where a small kerosene blend makes practical sense. In cold climates like Central Maine, #2 diesel can gel at low temperatures, clogging fuel filters and leaving your fleet stranded. Adding kerosene, typically no more than 20% of the total fuel volume, lowers the gel point and keeps fuel flowing.

This approach is most common during extreme cold snaps. A few important caveats apply:

For Central Maine operations running construction equipment, delivery vans, or farm machinery, a better long-term solution is winter-blend diesel, already formulated to handle cold temperatures without the trade-offs of kerosene.

What are the risks of running kerosene in a diesel engine?

Using kerosene as a primary fuel source, rather than an emergency additive, creates real operational risk. Here’s what can go wrong.

Injector and pump damage: Diesel injectors rely on fuel for lubrication. Kerosene’s lower lubricity accelerates wear, leading to costly repairs.

Reduced power output: Kerosene has a lower energy content than diesel. You’ll notice decreased performance and fuel economy, especially under heavy load.

Emissions and compliance issues: Depending on how the equipment is classified—on-road versus off-road—using non-compliant fuels can create regulatory headaches.

For businesses in Paris, ME, and the surrounding Central Maine area, downtime isn’t just an inconvenience. It affects job schedules, contract timelines, and customer relationships.
